Source tables: Housing totals · Tenure · Building types · Year built · Median year built. Survey estimates and their margins of error are shown as published; these are not October 2026 counts. The separate population reference uses Census Vintage 2025.
For a rented home, confirm who can authorize alterations. In a shared building, ask about access and work rules. A citywide construction period does not establish the age, condition or safety requirements of an individual home; check the property records and the specific project.
